摘要： The present invention includes a method and system for detecting and locating a breach of a pipe in nested multi-pipe petroleum wells through the use and measurement of pressure valves and pressure sensors. The system “locates” breaches in the sense that it determines in which pipe or pipes, if any, in a nested multi-pipe production well the breach exists. The method comprises the steps of, first, connecting at least two of the well pipes of a nested multi-pipe production well to a collection reservoir to allow fluid communication from the well into the reservoir; second, sealing the well pipes to maintain the pressure therein; third, measuring a pressure parameter within each of said at least two well pipes until said pressure parameter indicates a stabilization of pressure therein; fourth, altering the pressure within one of the well pipes; fifth, measuring a pressure parameter within the other well pipes; and sixth, stabilizing the pressure in the well pipe within which the pressure was previously altered.According to one aspect of the invention, a system controller executes a predefined program, which detects breaches between pipes comprising the production well by selectively altering pressure into the pipes and measuring the pressure change within the remaining well pipes. A change in the pressure indicates that the well pressure has escaped the well pipe through a breach therein. In this manner, the presence and location of breaches can be detected, and appropriate repair steps undertaken, before substantial contamination of the environment occurs.

摘要： A method and system for containing escaping hydrocarbon fluid from a well pipe of a production well. Suppression of the hydrocarbon fluid to a level below the breach location using a control fluid allows the breach to be repaired through the installation of a containment sleeve at the location of the breach. After collecting the escaping hydrocarbon fluids with a containment sleeve, the hydrocarbon fluid is routed to a collection reservoir from which it may be easily recovered without causing environmental damage. This process occurs with minimal downtime of the production well with the added environmental benefit of remediation of earth contaminated by the hydrocarbon breach.
